This project will develop an integrated water-sensor package capable of measuring multiple contaminants and common water quality indicators, such as pH, ORP, and temperature. A proof-of-concept prototype will be integrated with a commercial, off-the-shelf trace-metal-concentration measurement device to accurately detect trace metal concentrations on a real-time, continuous basis. The project will perform concentration measurements of multiple contaminants and accurate trace metal detection (Se, As, Hg), perform measurements and integration of commercial off the shelf water quality indicators (i.e. pH, TDS, etc.), and use demonstration unit for extended in-field testing of flue gas desulfurization (FGD) wastewaters at a coal fired power plant at the Water Research Center in Cartersville, GA and validate results for accuracy and reliability through comparison with the gold-standard analysis method provided by the onsite ICP-MS.

Project Benefits

Ability to monitor and detect contaminant concentration levels in FGD wastewater discharge in coal fired power plants, reduction in recurring operating and off-site laboratory analysis costs by minimizing required FGD wastewater treatment reagents and equipment, and closed loop control of contaminant concentrations in effluent discharge resulting in high level of confidence of compliance with EPA discharge guidelines.
